How to Make an Off Grid Shower

The first thing I made when I started putting together my portable cabin (that's what I'm calling it now) was the bathroom. I want a hot shower every morning and access to a toilet 24/7.

It took me a little bit before I got everything worked out, but I made an on-demand hot water shower (using rainwater) and composting toilet for probably about $3,000, not counting my time. 

Here's how I made mine-

I built an 8'x10' rain collector on my roof. The water goes into a downspout, through a filter and into my water tank. Overflow water can go into a reserve tank. 

When I want a shower I just pull a switch which activates the 12 volt electric pump which in turn activates the propane fired hot water heater.

I've got 200 watts of solar and two deep cycle batteries.

Water heater- Camplux 5L 1.32 GPM- $150
Pump- 3 GPM- $60
Shower stall 32"x32"- $250
200 watt solar system- $400
Two 12V batteries- $500
Filter, hoses, pipe, lumber, etc, etc,- $1,000
